Answer 1

Resposta:

A) x²+9x²-12x²=10x²-12x²=-2x²

B) 6x²-(3x²-12x²+x²-5x²)=6x²- (-13x²) =6x²+13x²=19x²

C) (5x²+2x+1)+(3x²-4x-3)-(2x²+x-4)

=6x²-x-6

D) (9x)×(2x³y) = 18x⁴y

E) (9y⁵)÷(3y)

F) (8y³-4y²+16y)÷(2y) =4y²-2y+8

G)

(12a⁴b⁴c⁴-18a³b³c³+6a²b²c²)÷(6a²b²c²)

(2a⁴b⁴c⁴-3a³b³c³+a²b²c²)÷(a²b²c²)

=2a²b²c² -3abc+1
